SHOE-RELASTING MACHINE.

Specification of Letters Patent.

Patented Aug. 12, 1919.

Application filed February 3, 1919. Serial No. 274,727.

To all whom it may concern:

Be it known that 1, ROBERT W. BLArsDELL,

a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented certain new and useful Improvements in Shoe- Relasting Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in means for lasting shoes, and it is more particularly directed to the provision of a machine for performing the second lasting operation on what is known as turned shoes, such shoes being lasted and stitched inside out, and then turned and subjected to a second lasting operation to impart their final shape thereto.

It is primarily the object of my invention to provide a machine whereby a shoe may be snugly fitted on the forward portion of the last in a most rapid and eflicient manner, and without making unusual demands on the strength of the operator in contradistinction to the manual operation now employed of pounding the last against a table or other support to effect a snug engagement of the shoe thereon.

A further object of my invention is to provide a means for inserting a shoe on a last which does not require pounding of the last, with the consequent damage entailed thereby.

A still further object resides in the pro vision of a lasting machine adapted to perform the functions above set forth and which has its parts so arranged as to most readily receive a shoe and last for the operation of the machine to procure economy of the operators time and permit a most rapid operation of the machine.

With the above and other objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts as hereinafter more particularly described and defined by the appended claims.

In the accompanying drawings:

Figure 1 is a side elevational view of a shoe relasting machine embodying my invention, portions of the structure being broken away. 7 V

Fig. 2 is a plan view of the machine.-

Fig. 3 is a detail sectional view through the movable jaw carrying member of the machine on a plane indicated by the line 3-3 of Fig. 1.

Referring now more particularly to the drawings, 5 designates a'table or other support to which my machine is secured. The present embodiment of my invention includes a substantially U-shaped base plate 6 having apertures 7 in its intermediate portion for receiving screws or other fastening means for securing the plate to the edge portion of the table or other support, with the ends of the plate projecting beyond the support. A sole supporting post 8 rises from one end of the plate, carrying an upper head having an inclined face 9 provided with a covering-10 of leather or other suitable sheathing material. A heel supporting post 11 rises from the other end of the plate and is provided with a recess 12 adapted to snugly receive the heel portion of a last A, when the sole portion of the last rests on the inclined face 9. 111 Fig. 1 of the drawings, a turned shoe B is shown partially mounted on the forward portion of the last, the rear end of the sole piece S of said shoe being loose as shown.

For drawing the shoe snugly onto the forward portion of the last, a channel bar 13 has one end portion pivoted to an inwardly extending lug 14 on the end of the base plate 6 adjacent the sole supporting post 8, the web portion of the bar being disposed upwardly and terminatin in an upwardly extending fiXed jaw 15. &he sides of the bar are eX- tended past this jaw to form pivot ears mounting a movable jaw 16 cooperating with the jaw 15 to clamp the rear end portion of th sole therebetween, the opposed faces of the jaws being provided with serrations to afiord a positive grip. An arm 17 extends from the movable jaw into the channel of the bar and is pivotally connected with a yoke 18 in which is threaded one end of a link 19 having its other end threaded in a yoke 20 pivoted to the intermediate portion of a treadle lever 21, which has one end portion pivoted to a suitable frog bracket 22. The treadle is normally raised by a contractile spring 23 connected therewith and with the table 5 or other support. The channel bar 13 constituting the movable jaw carrying member of my machine, is yieldably urged to raised position by a contractile coil spring 24 secured thereto and to the pQs t 8, upward movement of the bar being adthe jaw 15 to exert a gripping action on the A sole piece, and will then draw the sole piece downwardly and rearwardly, thus drai'ving the forward portion of the shoe snugly onto the forward portion of the last, the completion of the lasting operation being effected by removing the last from the supports and drawing the heel portion of the last fromthe heel portion of the shoe in the co'nventional manner.

My invention is particularly adapted for performing the second lasting operation on turned shoes, such shoes being first lasted and stitched inside out, and then turned and subjected to the second lasting operation to effect the final shape of the shoe. Heretofore, it has been eustoma'ry to mount the shoe upon the last, in the second lasting op eration, by grasping the shoe, with the last partially inserted therein and then pounding the heel portion of the last against the table. This manual operation requires the exercise of an unusual degree of strength on the part of the operator, thus requiring picked operators and in addition damages the heel portions of the lasts in a manner which materially impairs their usefulness and requires otherwise unnecessary replacements from time to time. 7

My improved machine will effect the mounting of the shoe on the last in a most ready manner, without damaging the last whatever and without requiring the exercise of an unusual degree of strength by reason ofthe leverage and foot action involved. It is noted that when the bar 13 is raised by the spring 24, and the treadle is raised by the spring 23, the jaws are held in spread relation whereby to facilitate the insertion of the heel piece, of the shoe between said jaws as the last is seated on the supports, thus conducing to an exceeding rapid operation of the machine.

While I have shown and described a preferred embodiment of my invention, it will be understood that various" phanges and modifications of structure may be resorted to without departing in any manner from the spirit of the invention, as defined by the appended claims.

What is claimed is:

1. A relasting machine including means for afiording stationary support for a last and means movable with respect to said support means and engageable with the sole of a shoe mounted on a last on said support means for; drawing the shoe on the forward portion of the last.

2. A relasting machine including a last support having a stationary abutment portion for the heel of a last, and movable means 'engageable with the sole of a shoe mounted 011 a last on said support for drawing the shoe on the forward portion of the last.

3. A relasting machine including a last heel support, a last sole support, and means movable below said supports and engageable with the sole of a shoe mounted on a last seated on said supports for drawing the shoe on the last.
